Make vessels more cost-efficient and environmentally friendly

Vessel speed and extensive marine biofouling are two reasons for high fuel expenses. With fuel accounting for up to 50% of marine transportation costs, it’s no wonder shipping companies are finding ways to not only avoid zones with strong counter currents, but also accurately predict the extent of biofouling on their vessels.


Our solutions help optimise route planning to reduce fuel consumption up to 5% and operational costs. Clients gain access to hourly global current data thanks to the integration of satellite measurements and globally leading hydrodynamic models. Furthermore, we have solutions that predict biofouling on vessel hulls. You can keep biofouling at a minimum with our biofouling service, which can predict the extent of biofouling on ships, so you know when to schedule diver inspections and hull cleaning. In short, get access to high-quality current data and biofouling predictions at any time, wherever you are.
